I have to post this because this is about everything this blog is about: classical liberalism is the really progressive movement.

We all know it: to lose weight we all need to eat less and/or excercise more. Even Stephen Hawkings said so : "We eat too much and move too little". Givin the fact that Hawkings cannot move at all, while he seems to be almost anorexic, this comment is more than just a little ironic. Because the thing is this: while you indeed need to be in a caloric deficit to become smaller the idea that you can ONLY do this by moving more and eating less is overly simplistic and woefully incomplete.

Just a short article to get the site running again. Economic textbooks generally are rife with the concept of "market failures". The most important are externalities (positive and negative), public goods and monopolies.
